FIG. 1 is a schematic top diagram of a display device according to thefirst embodiment of the disclosure. FIG. 2 is an enlarged schematicdiagram of the region R in FIG. 1 .

Referring to FIGS. 1 and 2 , a display device 1 of the disclosure may bea non-self-luminous display device. The non-self-luminous display devicemay include liquid crystal display device, but the disclosure is notlimited thereto. The liquid crystal display device may be a liquidcrystal display device that is in a dark state when no voltage isapplied and is in a bright state when a voltage is applied, or may be aliquid crystal display device that is in a bright state when no voltageis applied and is a dark state when a voltage is applied, but norestriction is imposed here. For the detailed structure of the liquidcrystal display device, reference can be made to the existing design,which will not be repeated here.

The display device 1 may include a display mode and a camera mode. Inthe display mode, the display device 1 provides a display function. In acamera mode, the display device 1 provides a shooting function.According to different requirements, the display device 1 may alsoprovide a display function in the camera mode. For example, the displaydevice 1 may display the acquired image while acquiring the image of ashooting subject, but the disclosure is not limited thereto.

In detail, the display device 1 may include a camera region R1. FIG. 1schematically shows a square camera region R1, and the camera region R1is disposed adjacent to one of the corners of the display device 1.However, it should be understood that the number, the dispositionposition, or the top view shape of the camera regions R1 and the likemay be changed as required.

The camera region R1 may be configured to obtain an image of a shootingsubject. In detail, referring to FIG. 2 , the camera region R1 mayinclude multiple camera pixels Pc. The driving method of the displaydevice 1 includes: placing the multiple camera pixels Pc in a state thata light beam is not allowed to pass through, in a display mode; andplacing the multiple camera pixels Pc in a state that a light beam isallowed to pass through, in a camera mode. In other words, in thedisplay mode, the multiple camera pixels Pc are in a state that a lightbeam is not allowed to pass through; that is, the multiple camera pixelsPc are in a dark state in the display mode. On the other hand, in thecamera mode, the multiple camera pixels Pc are in a state that a lightbeam is allowed to pass through; that is, the multiple camera pixels Pcare in a bright state in the camera mode.

With the multiple camera pixels Pc being in a state that a light beam isallowed to pass through, in the camera mode, it helps to increase thelight transmittance of the multiple camera pixels Pc in the camera mode,such that the camera module located in the camera region R1 can receivemore image light beams from the shooting subject, thereby helping toimprove the imaging quality. In some embodiments, the camera region R1may also include other sensing devices, such as fingerprint sensor, irissensor, retina sensor, face sensor, in sensor, a movement sensor,gesture sensor, proximity sensor or other suitable sensors; thedisclosure is not limited thereto.

With the multiple camera pixels Pc being in a state that a light beam isnot allowed to pass through, in the display mode, in some embodiments,the multiple camera pixels Pc may be equivalent to a black matrix in thedisplay mode. That is, in the display mode, the multiple camera pixelsPc may be configured to block light leakage, block stray light, or blockelements that are not intended to be seen by the user, or may beconfigured to enhance contrast. In some embodiments, the camera regionR1 may further include multiple first display pixels Pm1. The multiplefirst display pixels Pm1 may provide a display function in the displaymode. According to different requirements, the multiple first displaypixels Pm1 may also provide a display function in the camera mode.

For example, the first display pixel Pm1 may emit a single color light,and the multiple first display pixels Pm1 may include multiple firstblue pixels Pm1, multiple first green pixels Pm12, and multiple firstred pixels Pm13. Each of the multiple first blue pixels Pm11, themultiple first green pixels Pm12, and the multiple first red pixels Pm13may be disposed in a first direction D1, and the multiple first bluepixels Pm11, the multiple first green pixels Pm12, and the multiplefirst red pixels Pm13 may be alternately disposed in a second directionD2. The second direction D2 intersects the first direction D1, and thesecond direction D2 may be perpendicular to the first direction D1, butthe disclosure is not limited thereto. The first direction D1 and thesecond direction D2 are both perpendicular to a thickness direction(such as a third direction D3) of the display device 1. However, itshould be understood that the color type, number, shape or dispositionof the pixels in the multiple first display pixels Pm1 may be changedaccording to requirements. In some embodiments, the first direction D1may be, for example, an extending direction of a scan line (not shown)in the display device 1, but the disclosure is not limited thereto.

In some embodiments, the multiple camera pixels Pc and the multiplefirst display pixels Pm1 may be alternately disposed in the seconddirection D2. FIG. 2 schematically shows a pixel unit U, and the labeledpixel unit U includes one camera pixel Pc and one first blue pixel Pm11.However, it may be understood from FIG. 2 that the camera region R1 mayinclude the multiple pixel units U, and each of the multiple pixel unitsU may include one camera pixel Pc and one first display pixel Pm1 l(such as one first blue pixel Pm11, one first green pixel Pm12 or onefirst red pixel Pm13). In other embodiments, each of the multiple pixelunits U may also include a camera pixel Pc and multiple first displaypixels (such as a combination of a first blue pixel Pm11, a first greenpixel Pm12, and a first red pixel Pm13, but the disclosure is notlimited thereto).

The display device 1 may further include a display region R2. Thedisplay region R2 is adjacent to the camera region R1. FIG. 1schematically shows that the camera region R1 is located at an upperright corner of the display region R2. However, the respective number,the relative disposition relationship, the top view shape, the arearatio or the like of the camera region R1 and of the display region R2may be changed according to requirements. For example, the camera regionR1 may also be located at an upper left corner of the display region R2or in the middle of one of the sides of the display region R2.Alternatively, the display device 1 may include the multiple cameraregions R1, and the multiple camera regions R1 may be located atmultiple corners or at the middle of multiple sides of the displayregion R2, or a combination of the above, but the disclosure is notlimited thereto.

In the display mode, the display region R2 may provide a displayfunction. According to different requirements, the display region R2 mayalso provide a display function in the camera mode. For example, thedisplay region R2 and the camera region R1 may jointly provide the imagecaptured by the camera region R1 in the camera mode, but the disclosureis rot limited thereto.

In detail, proceeding to refer to FIG. 2 , the display region R2 mayinclude multiple second display pixels Pm2. The second display pixel Pm2may emit a single color light. The multiple second display pixels Pm2may include multiple second blue pixels Pm21, multiple second greenpixels Pm22, and multiple second red pixels Pm23. Each of the multiplesecond blue pixels Pm21, the multiple second green pixels Pm22, and themultiple second red pixels Pm23 may be disposed in the first directionD1, and the multiple second blue pixels Pm21, the multiple second greenpixels Pm22, and the multiple second red pixels Pm23 may be alternatelydisposed in the second direction D2. However, it should be understoodthat the color type, number, or disposition of the pixels in themultiple second display pixels Pm2 may be changed according torequirements.

In some embodiments, a resolution of the camera region R1 may be lowerthan a resolution of the display region R2 so as to reduce negativeimpact of diffraction or interference of the light beam (such as theimage light beam from the shooting subject) on the imaging quality. Inother embodiments, a pixel pitch d1 in the first direction D1 of twoadjacent first red pixels Pm13 in the camera region R1 is greater than apixel pitch d2 in the first direction D1 of the two adjacent first redpixels Pm13 in the display area R2.

In some embodiments, the multiple camera pixels Pc, the multiple firstdisplay pixels Pm1 (including the multiple first blue pixels Pm11, themultiple first green pixels Pm12, and the multiple first red pixelsPm13), and the multiple second display pixels Pm2 (including themultiple second blue pixels Pm21, the multiple second green pixels Pm22,and the multiple second red pixels Pm23) may have a same polarity. Forexample, by frame inversion, the polarities of the multiple camerapixels, the multiple first display pixels Pm1, and the multiple seconddisplay pixels Pm2 may be made all positive (represented by “+” in FIG.2 ), or the polarities of the multiple camera pixels Pc, the multiplefirst display pixels Pm1, and the multiple second display pixels Pm2 maybe made all negative (not shown in FIG. 2 ; represented by “−” in FIG. 4). When an absolute value of a voltage difference is fixed, the polaritymay be changed by making the voltage of the pixel electrode higher thanthe voltage of the common electrode or making the voltage of a pixelelectrode lower than the voltage of a common electrode. Through polaritychange, feature damage caused by liquid crystal molecule orientation toalways be fixed in one direction can be reduced. It should be understoodthat the camera pixel Pc, the first display pixel Pm1, and the seconddisplay pixel Pm2 each have a pixel electrode and a common electrode,where the pixel electrodes of the camera pixel Pc, of the first displaypixel Pm1, and of the second display pixel Pm2 are separated from eachother. On the other hand, the common electrodes of the camera pixel Pc,of the first display pixel Pm1, and of the second display pixel Pm2 maybe separated from each other or connected to each other (such as beingdifferent parts of a continuous electrode). Based on different designconsiderations (such as light transmittance, contrast, or light leakageblocking, etc.), in each of the multiple pixel units U, a ratio of anarea of the camera pixel Pc to an area of the one (or more) firstdisplay pixels Pm1 may fall within a range of 0.04 to 25 (0.04≤arearatio≤25). For example, one pixel unit U may include one camera pixel Pcand at least three first display pixels Pm1, and the ratio of the areaof one camera pixel Pc to a total area of the at least three firstdisplay pixels Pm1 may fall within a range of 0.04 to 25. In someembodiments, the area of the first display pixel Pm1 may be, forexample, the area of the pixel electrode of the first display pixel Pm1,and the area of the camera pixel Pc may be, for example, an area of thepixel electrode of the camera pixel Pc. In other embodiments, the areaof the first display pixel Pm1 may be, for example, an area of asmallest imaginary rectangle surrounding the pixel electrode of thefirst display pixel Pm1, and the area of the camera pixel Pc may be, forexample, an area of another smallest imaginary rectangle surrounding thepixel electrode of the camera pixel Pc, but the disclosure is notlimited thereto. The material of the pixel electrode and the commonelectrode may include a transparent conductive material, such as indiumtin oxide (ITO), but the disclosure is not limited thereto.

According to different requirements, the display device 1 may furtherinclude other elements or film layers. For example, the display device 1may further include multiple active elements AD and multiple colorfilter patterns CF. The multiple active elements AD and the multiplecolor filter patterns CF are located outside the multiple camera pixelsPc (that is, each camera pixel Pc may not need to include the activeelement AD and the color filter pattern CF) and located in the multiplefirst display pixels Pm1 and the multiple second display pixels Pm2. Indetail, the color filter pattern CF may at least partially overlap thepixel electrodes of the multiple first display pixels Pm1 and the pixelelectrodes of the multiple second display pixels Pm2, and the colorfilter pattern CF may not need to overlap the pixel electrodes of themultiple camera pixels Pc.

The active element AD may be used as a switching element. For example,the active element AD may include a thin film transistor, but thedisclosure is not limited thereto. In some embodiments, each displaypixel (such as the first blue pixel Pm11, the first green pixel Pm12,the first red pixel Pm13, the second blue pixel Pm21, the second greenpixel Pm22, or the second red pixel Pm23) may include one or more activeelements AD. Further, at least one active element AD in each displaypixel is electrically connected to a scan line (not shown) and a dataline (not shown) in the display device 1 so as to control signal input,but the disclosure is not limited thereto.

The color filter pattern CF allows specific light beams to pass throughand filters out the remaining light beams so as to provide colordisplay. For example, the multiple color filter patterns CF may includemultiple blue filter patterns CF1, multiple green filter patterns CF2,and multiple red filter patterns CF3. The multiple blue filter patternsCF1 are located in the multiple first blue pixels Pm11 and the multiplesecond blue pixels Pm21; the multiple green filter patterns CF2 arelocated in the multiple first green pixels Pm12 and the multiple secondgreen pixels Pm22; and the multiple red filter patterns CF3 are locatedin the multiple first red pixels Pm13 and the multiple second red pixelsPm23.

Compared with the first display pixel Pm1 and the second display pixelPm2 for displaying images (including grayscale and color changes), thecamera pixel Pc is configured to adjust the light transmittance. Forexample, the camera pixel Pc switches between the camera mode and thedisplay mode. Since the camera pixel Pc may not need to provide colordisplay, the camera pixel Pc may not need to include the color filterpattern CF. In some embodiments, the camera pixel Pc may be electricallyconnected to one or more pins that output high voltage and low voltagein a driving element (such as a driver chip) so as to switch between thedisplay mode and the camera mode. In this way, the camera pixel Pc maynot need to include the active elements AD. For example, the displaydevice 1 may further include a wire 10 and an outer lead bonding (OLB)region R3 The outer lead bonding region R3 may be provided with, forexample, a flexible printed circuit hoard (FPC), a chip on film (COF) orrelated display driving circuits/elements. Moreover, the multiple camerapixels Pc may be electrically connected to the driving circuit or thedriving element in the outer lead bonding region R3 through the wire 10.In some embodiments, the wire 10 may be in a different layer from thescan line and the data line. For example, the wire 10 may be disposedabove the scan line and the data line and electrically connected to thepixel electrode in the camera pixel Pc through a conductive through holeCV, but the disclosure is not limited thereto. In some embodiments, thewire 10 may be fabricated together with the pixel electrode or thecommon electrode, that is, the wire 10 may be in the same layer as thepixel electrode or the common electrode.

With the multiple camera pixels Pc being electrically connected to thedriving elements through the wire 10, there is no need to provide activeelements in the camera pixels Pc, thereby helping to reduce the numberof wires or elements required, increase the aperture ratio, or reducethe diffraction or interference of light beams. Moreover, referring toFIG. 2 , the multiple camera pixels Pc may have a same polarity, suchthat the multiple camera pixels may be electrically connected to thewire 10, thus the number of the wires 10 connected between the multiplecamera pixels Pc and the driving element can be reduced, and the wire 10has low influence on the border. In some embodiments, as shown in FIG. 1, the multiple camera pixels Pc may be electrically connected to thedriving element through the wire 10. In other embodiments, the number ofwires 10 may also be increased, and different wires 10 may be connectedto multiple pins of the driving element so as to reduce theresistive-capacitive loading. With the design of electrically connectingthe multiple camera pixels Pc and the driving element through themultiple wires 10, the multiple wires 10 may extend from the multiplecamera pixels Pc through a same side or an opposite side of the displayregion R2 (such as the left and right sides of the display region R2 asshown in FIG. 1 ) to the driving element. Considering the influence ofinconsistent wire length on impedance, it is possible to make a longerwire have a larger line width and a shorter wire to have a smaller linewidth, or make multiple wires 10 extend from the multiple camera pixelsPc through the same side of the display area R2 to the driving element,such that wires of different lengths have the same or close to the sameresistive-capacitive loading (RC loading). Alternatively, the cameraregion R1 may also be disposed in the center so as to maintain thedesign of double-sided routing.

In some embodiments, for example, an oscilloscope may be configured tomeasure the signal and/or the waveform provided by the data line (notshown) or the wire 10. When operating an electronic device, at least onedata line or at least one wire 10, for example, provides a square wavesignal. The square wave signal can be, for example, a positive/negativealternating current signal, and the positive/negative polarities of thefirst display pixel Pm1, the second display pixel Pm2, and the camerapixel Pc can be determined according to the positive/negative of thesquare wave signal, but this disclosure is not limited such thereto.

FIG. 3 is a schematic timing diagram for displaying state switching ofmultiple camera pixels. Referring to FIG. 3 , the transition time of themultiple camera pixels (such as the switching time between the displaymode and the camera mode) increases as the number of camera pixels inthe camera region increases. In some embodiments, the transition time ofthe camera pixel may be at least 20 times the transition time of thedisplay pixel (such as the first display pixel or the second displaypixel). At this time, the state switching of the multiple camera pixelsmay be made to occur in the blanking time between two adjacent frames(such as the Nth frame and the N+1th frame), that is, the mode of thecamera pixel is switched in the blanking time between the intervals ofthe adjacent two updated display screens. In other embodiments, thecamera pixels may be connected to multiple wires so as to reduce thecapacitive loading. Therefore, the camera pixels may be switched at thesame time as is the Nth frame or the N+1th frame (that is, the screenswitching of the camera pixels do not need to occur in the blanking timebetween the intervals of two frames).

FIGS. 4 to 8 are schematic partial top diagrams of display devicesaccording to the second embodiment to the sixth embodiment of thedisclosure, respectively. In the following embodiments, the same orsimilar elements will use the same or similar reference numerals, andredundant description will be omitted. Moreover, the features indifferent embodiments may be mixed and matched arbitrarily as long asthey do not violate the spirit of the disclosure or conflict with eachother, and simple equivalent changes and modifications made inaccordance with this specification or claims are still within the scopeof this disclosure.

Please refer to FIG. 4 , in a display device 1A, the multiple firstdisplay pixels Pm1 (including the multiple first blue pixels Pm11, themultiple first green pixels Pm12, and the multiple first red pixelsPm13) and the multiple second display pixels Pm2 (including the multiplesecond blue pixels Pm21, the multiple second green pixels Pm22, and themultiple second red pixels Pm23) have the same polarity, and thepolarities of the multiple camera pixels Pc are opposite to thepolarities of the multiple first display pixels Pm1 and the multiplesecond display pixels Pm2. In other words, in the pixel unit U, thecamera pixel Pc and the first display pixel Pm1 (such as the first bluepixel Pm11, the first green pixel Pm12, or the first red pixel Pm13)have opposite polarities. By making the multiple camera pixels Pc andthe multiple first display pixels Pm1 in the camera region R1 haveopposite polarities, it is helpful to increase the light transmittance.In the present embodiment, the polarity of any one of the multiplecamera pixels Pc, the multiple first display pixels Pm1, and themultiple second display pixels Pm2 may be switched by, for example,frame inversion.

Referring to FIG. 5 , in a display device 1B, each of the multiplecamera pixels Pc, the multiple first display pixels Pm1, and themultiple second display pixels Pm2 has an alternating positive/negativepolarity in the first direction D1, and each of the multiple camerapixels Pc, the multiple first display pixels Pm1, and the multiplesecond display pixels Pm2 has the same polarity in the second directionD2. Moreover, in the pixel unit U, the camera pixel Pc and the firstdisplay pixel Pm1 (such as the first blue pixel Pm11, the first greenpixel Pm12, or the first red pixel Pm13) have the same polarity. In someembodiments, the camera pixels Pc of opposite polarities may beconnected to multiple pins of the driving element through differentwires (such as the wire 10 and a wire 10B). Using multiple pins tocontrol the state of the multiple camera pixels Pc (such as display modeor camera mode) helps reduce the resistive-capacitive loading.

As mentioned above, considering the influence of inconsistent wirelengths on impedance, it is possible to make a longer wire have a largerline width and a shorter wire to have a smaller line width, or makemultiple wires (such as the wire 10 and the wire 10B) extend from themultiple camera pixels Pc to the driving element through the same sideof the display area R2 (see FIG. 2 ), such that wires of differentlengths have the same or close to the same resistive-capacitive loading.Alternatively, the camera region R1 may also be disposed in the centerso as to maintain the design of double-sided routing.

In the present embodiment, the polarity of any one of the multiplecamera pixels Pc, the multiple first display pixels Pm1, and themultiple second display pixels Pm2 may be switched by, for example,column inversion. The polarity conversion method of column inversionhelps to reduce crosstalk.

Referring to FIG. 6 , the main difference between a display device 1Cand the display device 1B of FIG. 5 is: in the pixel unit U of thedisplay device 1C, the camera pixel Pc and the first display pixel Pm1(such as the first blue pixel Pm11, the first green pixel Pm12, or thefirst red pixel Pm13) have opposite polarities, which helps to increasethe light transmittance.

Please refer to FIG. 7 , the main difference between a display device 1Dand the display device 1C of FIG. 6 is: in the display device 1D, themultiple camera pixels Pc, the multiple first display pixels Pm1, andthe multiple second display pixels Pm2 are disposed 90 degrees rotated.In other embodiments, the polarity design of various pixels in thedisplay device 1D may also be changed to the polarity design shown inFIG. 2 , FIG. 4 , or FIG. 5 , which will not be repeated here.

Please refer to FIG. 8 , the main difference between a display device 1Eand the display device 1C of FIG. 6 lies in the design of the pixel unitU. In the display device 1E, the pixel unit U includes a camera pixel Pcand three first display pixels Pm1 (such as one first blue pixel Pm11,one first green pixel Pm12, and one first red pixel Pm13), and the ratioof the area of the camera pixel Pc to the total area of the three firstdisplay pixels Pm1 may fall within a range of 0.04 to 25. In otherembodiments, one pixel unit U may include one camera pixel Pc andmultiple first display pixels Pm1. However, it should be understood thatdesign parameters such as the shape of the pixel unit U, the shape,number, distribution, disposition, and area ratio of the camera pixel Pcor the first display pixel Pm1 in the pixel unit U may be changedaccording to requirements. In other embodiments, the polarity design ofvarious pixels in the display device 1E may also be changed to thepolarity design shown in FIG. 2 , FIG. 4 , or FIG. 5 , which will not berepeated here.

In summary, in the embodiments of the disclosure, with the multiplecamera pixels being in a state that a light beam is allowed to passthrough, in the camera mode, it helps to increase the lighttransmittance of the multiple camera pixels, in the camera mode, suchthat the camera module located in the camera region can receive moreimage light beams from the shooting subject, thereby helping to improvethe imaging quality. With the multiple camera pixels being in a statethat a light beam is not allowed to pass through, in the display mode,which helps to block light leakage, block stray light, block elementsthat are not intended to be seen by the user, or improve contrast.

In some embodiments, the resolution of the camera region may be lowerthan the resolution of the display region so as to reduce the negativeinfluence of the diffraction or interference of the light beam on theimaging quality. In some embodiments, the multiple camera pixels may beelectrically connected to the driving element through the wire so as toreduce the number of wires or elements required, to increase theaperture ratio, or to reduce the diffraction or interference of thelight beam. In some embodiments, a wire may be configured toelectrically connect the multiple camera pixels and the driving element,so as to reduce the influence of the wire on the border. In someembodiments, the number of wires may be increased, and different wiresmay be connected to multiple pins of the driving element so as to reducethe resistive-capacitive loading. In some embodiments, the line width ofthe wire, the disposition position of the wire, or the position of thecamera region may be adjusted so as to make the wires of differentlengths have the same or close to the same resistive-capacitive loading.In some embodiments, the state switching of the multiple camera pixelsmay be made to occur in a blanking time between two frames. In someembodiments, the light transmittance can be increased by making themultiple camera pixels and the multiple first display pixels in thecamera region have opposite polarities. In some embodiments, by columninversion, the crosstalk can be reduced by changing the polarity.

The above embodiments are only configured to illustrate the technicalsolutions of the disclosure, but the disclosure is not limited thereto.Although the disclosure has been described in detail with reference tothe foregoing embodiments, those of ordinary skill in the art shouldunderstand that they may still modify the technical solutions describedin the foregoing embodiments, or equivalently replace some or all of thetechnical features.
